'Fundamentals' Trackies

Fundamentals Performance Trackies

Discipline in Motion. Comfort in Stillness.

Whether you're pushing limits at the gym or embracing well-earned downtime, our Fundamentals Trackies are built for every part of your lifestyle. Lightweight yet durable, tapered yet relaxed—these are the go-to bottoms for those who live with purpose, both in movement and rest.

Made from breathable, medium-weight polyester with a performance cut, they offer the freedom to move, sweat, or chill with total ease.

Features & Feel

Designed for Motion
With a slim, tapered leg and ankle zips with zip guards, these trackies move with you—whether you're stretching, sprinting, or lounging.

Stay Secure, Stay Focused
Two zipped side pockets keep your essentials safe and out of sight, so you can stay present in your training or your chill.

Everyday Performance Fit
An elasticated waistband with internal drawcord allows you to customise the fit. Built for form and function.

Built with Purpose
Made from 100% polyester, these are lightweight at 250gsm and WRAP certified for ethical manufacturing.

The Symbol

On the left thigh, you'll find our Fundamentals logo—simple, powerful, and understated.
Down the right lower leg, a bold red/orange Bushido kanji print makes its mark.
Bushido (武士道) represents the "code of honour and morals" followed by the Samurai—now honoured by martial artists worldwide. Wear it as a symbol of integrity, focus, and everyday discipline.

Pairs perfectly with the Fundamentals Logo Hoody for a complete set rooted in style and meaning.
